Anthurium plant named &#39;Anthfube&#39;

ABSTRACT

A new  Anthurium  plant named ‘ANTHFUBE’ particularly distinguished by having shiny, blistered, dark brown, cordate and durable spathes that retain the original color for a very long period of time, dark green and elliptical cordate, durable leaves, white spadix with green tips, early and rich flowering continuously throughout the year, and a plant height of 45.0 cm to 50.0 cm is disclosed.

Genus and species: Anthurium andraeanum L.

Variety denomination: ‘ANTHFUBE’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Anthurium,botanically known as Anthurium andraeanum L., and hereinafter referredto by the variety name ‘ANTHFUBE’. The new Anthurium plant is a productof a planned breeding program conducted by the inventor in Bleiswijk,the Netherlands. The objective of this breeding program was to create anew 45.0 cm to 50.0 cm height plant with shiny and blistered, darkbrown, cordate and very durable spathes.

The new variety originated from a cross-pollination made in December2010 in Bleiswijk, The Netherlands. The female parent was a brownAnthurium pot plant designated ‘17532-04’ (unpatented), and the maleparent was a brown Anthurium pot plant designated ‘20446-01’(unpatented).

A single plant was selected from the progeny of the stated cross inNovember 2012 and has been asexually reproduced repeatedly by tissueculture in Bleiswijk, The Netherlands over a 5-year period. The presentinvention has been found to retain its distinctive characteristicsthrough successive asexual propagations.

Plant Breeder's Rights for this variety have been applied for in theEuropean Union on Nov. 24, 2015. ‘ANTHFUBE’ has not been made publiclyavailable or sold anywhere in the world more than one year prior to theeffective filing date of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishingcharacteristics of this new variety when grown under normalhorticultural practices in Bleiswijk, The Netherlands:

-   -   1) Shiny and blistered, dark brown, cordate spathes;    -   2) White spadix with green tips; and    -   3) Dark green, elliptical cordate leaves.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctivecharacteristics of ‘ANTHFUBE’. The data which define thesecharacteristics were collected from asexual reproductions carried out inBleiswijk, The Netherlands. The plant history was taken on 44-week oldplants which were planted from tissue culture in 14 centimeter(diameter) pots and grown in a glass greenhouse between 19° C. and 24°C. Observations were made in December 2017. Color readings were takenunder 5000 lux natural light in the greenhouse. Color references areprimarily to The R.H.S. Colour Chart of The Royal Horticultural Societyof London (R.H.S.) (2015).

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

‘ANTHFUBE’ differs from the female parent plant ‘17532-04’ (unpatented)in that ‘ANTHFUBE’ has flat, dark brown spathes, cataphylls that aregreen at the base and dark red toward the tip, and spadix that aregreyed-yellow at the base and green at the top, whereas ‘17532-04’ hasslightly wavy, dark purple spathes, cataphylls that are greyed-purple,and spadix that are cream at the base and yellow-orange at the top.

‘ANTHFUBE’ differs from the male parent plant ‘20446-01’ (unpatented) inthat ‘ANTHFUBE’ has flat, dark brown spathes, cataphylls that are greenat the base and dark red toward the tip, and spadix that aregreyed-yellow at the base and green at the top, whereas ‘20446-01’ haswavy spathes that are a mix of brown and dark red, green cataphylls, andspadix that are greyed-orange at the base and dark yellow-green at thetop.

‘ANTHFUBE’ differs from similar commercial variety ‘ANTHCUFPA’ (U.S.Plant Pat. No. 28,032) in that ‘ANTHFUBE’ has dark brown spathes,whereas ‘ANTHCUPFA’ has dark red-purple spathes. Additionally,‘ANTHFUBE’ plants are medium to large sized, whereas ‘ANTHCUFPA’ plantsare small to medium sized.

‘ANTHFUBE’ differs from similar commercial variety ‘ANTHCIMWI’ (U.S.Plant Pat. No. 20,255) in that ‘ANTHFUBE’ has dark brown, flat spathesand green immature spadix, whereas ‘ANTHCIMWI’ has brown-red, cuppedspathes and green-yellow immature spadix. Additionally, ‘ANTHFUBE’plants are medium to large sized, whereas ‘ANTHCIMWI’ plants are smallto medium sized.

I claim:
 1. A new and distinct variety of Anthurium plant named‘ANTHFUBE’, substantially as illustrated and described herein.
